The invention relates to an on-board electrical system (20) for a motor vehicle. The invention relates to a high-voltage energy storage system (10), comprising a high-voltage network (22) for supplying voltage to one or more high-voltage consumers, comprising a high-voltage energy store (24), a main converter (32) for converting a high-voltage voltage present in the high-voltage network (22) into a predetermined low-voltage voltage present in a low-voltage network (28) in order to supply voltage to one or more low-voltage consumers, a battery management system (26) and a bypass converter assembly (36). The bypass converter arrangement (36) is designed to introduce the determined maximum permissible energy quantity from the high voltage network (22) into the low voltage network (28) during a parking phase of the motor vehicle (10). The invention also relates to a method for controlling such an on-board electrical system (20) and to a motor vehicle having such an on-board electrical system (20).
本发明涉及一种用于机动车的车载电网系统(20),其具有包括高压能量存储器(24)的用于为一个或多个高压用电器供应电压的高压电压网(22)、用于将存在于高压电压网(22)中的高压电压转换为预定的存在于低压电压网(28)中的低压电压以便为一个或多个低压用电器供应电压的主转换器(32)、电池管理系统(26)和旁路转换器组件(36)。所述旁路转换器组件(36)设置用于在机动车(10)的停放阶段期间将所确定的最大允许能量量从高压电压网(22)引入到低压电压网(28)中。本发明还涉及一种用于控制这种车载电网系统(20)的方法以及具有这种车载电网系统(20)的机动车。
